two

two: [OE] Two is an ancient word, traceable right back to Indo-European *duwo. Amongst its other descendants were Greek dúo, Latin duo (source of English deuce, double, dual, duet, duo, etc), Russian dva, and Welsh dau. In the Germanic languages, aside from English, it has evolved into German zwei, Dutch twee, Swedish tv?, and Danish to. Two represents the Old English feminine and neuter forms twā; the masculine twegen has become twain.
